My Dog Won't Stop Biting!!!!

My dog won't stop barking and biting people. He doesn't bite me or my husband but he does everyone else, including the kids. He doesn't draw blood or leave marks but it still drives us crazy.
Does anyone have any helpful suggestions, to help our 3 year old German Pincher with his nibbling problem?

Thinking back, I recall that my own dog went through a "nibbling" phase where she would bite a lot, though this was focused on the feet and more frequently the toes. Where is your German Pincher biting most often? It was a long time ago but I think she eventually outgrew it or my mom used positive reinforcement eg; rewarding her for not biting or stopping after she would loudly say "NO, STOP.". Has your dog had any other behavioral problems, is she an outside or inside pet? All of these factors can influence a dog's behavior. She could just be playing, in that case positive reinforcement might be the best way, she doesn't mean any harm.

A dog should never be allowed to bite, even in fun. they need to learn manners, just like kids do. Almost every little kids tries to bite his/her family members when they are a toddler; and has to learn that this is totally unacceptable behavior. Dogs are no different, and they have to be disiplined when they act aggressively towards other people.
I suggest putting the dog on a leash so you can control them when someone comes, and then make the dog sit quietly and not bark or lunge at the visitors. If your dog is not leash-trained, then this should be done first, so that the dog knows and obeys basic obedience commands, such as "sit" or "down".
When the company arrives, keep the dog beside you, and sitting or lying down, and scold him if he barks or growls.
Soon, he should learn what is expected behavior around other people. If he does not respond to voice commands, then a training aid, such as an ultra-sonic trainer might help. I got one from Amazon and it stopped my dog from barking right away, and it is harmless to the dog.

Your dog should definitely not be biting people. If he were to bite a stranger, they could call animal control and your dog could be taken away, and maybe even euthanized. You don't want that. There are many reasons why your dog could be biting people. It doesn't sound like he wants to hurt anyone, but is biting to appear intimidating to them. It would be best for both you and your dog, to find a professional dog behaviorist that can go out to your home and evaluate your dog. Once you know what is causing the problem, you can work with your dog to fix it, with the help of the dog behaviorist. It can be a little bit pricey, but it would be well worth it to fix this behavior. Good luck with your dog.
